Title: Electric accumulator with high energy density and rapid charge - utilises deceleration energy of vehicles on land, sea and in the air
IPC: H01M8/00
Filed: 1976-05-04
Abstract: The accumulator is combined with an electric traction vehicle in a system which provide sufficient power for the vehicle's propulsion, and recuperates the kinetic energy (E) available during deceleration and braking by using a "speed holder." The max. amt. of energy (E) can be recovered, even, if the vehicle is travelling below 3 ms. Energy (E) can be recovered by feeding it directly to an accumulator, or to a generator of hydrogen and oxygen. The system includes switching semiconductor elements which connect the vehicle traction motor windings in parallel or in series; and the air gap is automatically adjusted during deceleration so that the rotor becomes a generator. The electric energy thus produced can be fed to two electrodes in a water cell for producing H2 and O2. Numerous types of cell are included in 82 claims. Use of the accumulators can be instantaneously recharged in min. time and used for driving vehicles on land, sea, and in the air, or for driving machine tools.

Title: Costing for local telephonic communications - uses centralised processing system with programmed memory determining cost based on call duration
Inventor: PRUDHON LUCIEN PIERRE EMILE
IPC: H04M15/04
Filed: 1976-06-01
Abstract: A centralized processing system with programmed memory is used to determine costing for local telephonic communication based on length of time. The processing system transmits cost pulses to the calling subscriber cost counter and is able to discriminate between day or night tariffs. A mini or micro processor (P) controlling a telephonic costing system contains a programmed memory (Mp). A maintenance desk (Pm) permits checking of the system. The telephonic unjuctions are explored (Dex) and a pulse transmission circuit (Eip) transmits cost pulses via bus lines (0) to the processor. Interface circuits (Mo to M16) permit connection of telephonic junctions to the exploration (Dex) and pulse transmission circuits when commanded by the processor memory which contains the instruction addresses.

Title: Twisting of square metal rods - with tailstock anchoring one end while fixed headstock rotates until preset length is reached
IPC: B21D11/14
Filed: 1976-07-13
Abstract: A device for twisting square metal rod to a determined length consists of a bed shaped as an inverted 'U', a fixed headstock and a moving tailstock. The tailstock is equipped with four screws, equally pitched at 45 deg. to the machine axes. The lower pair are adjusted by a hexagonal headed key and the upper pair are knurled. This permits adjustment for a range of rod profiles and also allows rapid loading and unloading opf the workpiece. The headstock is equipped with four screwed handles in the capstan, which also allow for a range of rod sizes. When the headstock turns the rod is held fixed in the tailstock, and as it twists it shortens, until the stop contacts the tailstock.

Patent FR-2322496-A1 (FR)
IPC: G06T5/40
Filed: 1976-08-24
Abstract: Real time histogram equalization systems for a television type display that performs equalization with one or two dimensional processing on a local area or sliding window basis. For the two dimensional system, the intensity for any particular point in the image is adjusted according to a histogram of the area contained within a window immediately surrounding the point to be equalized. The histogram forming window provided by the system moves across the image in two dimensions both horizontally along each of a plurality of overlapping segments arranged parallel in the vertical dimension, and at each window position reassigned center picture elements are equalized. The processing of the histograms area or the sliding process is continued over the entire surface of the raster with the process being then repeated in a continuous fashion. The area being equalized for each window position may be selected equal horizontally and vertically to the respective amount of shifting along each segment between window positions and of the shifting of the window between adjacent segments. In order to process the histograms at the video rate and resolution the system computes mini or subhistograms from an area formed of a selected number of elements of the histogram in the horizontal dimension by the number of histogram lines in the vertical dimension of the window and sums the statistics of a selected number of the mini histograms to generate one histogram for equalizing the central area. In the continuous process the mini histograms are read out in parallel to form a plurality of histograms and multiple truncation maps which are stored in a selected number of RAM memories. Digital video is then processed through these transformed memories and stored in output buffers which may be required because of the multiplexing. In the system utilizing one dimensional processing, histograms are formed for the data of a selected number of lines in order to equalize the data of a selected line or lines and the histogram window area is moved vertically over the entire raster area.
